While the sizing was fine this didn't work at all

This small size is perfect for my 12 lb Havanese

I think this is the best size for her

Size was perfect and quality of the shirt is good

It's a really thin material, and size is not accurate

but i went size up in case and it worked

He did wear it very snugly, so the material was stretched and the seams were stressed, but that’s the purpose of the best, so I don’t think a larger size or looser wear would be ideal.

Can I send it back and get one the right size?

Quick shipping and just the right size for my dachshund.

The jacket was the perfect size for my border whippet it helps give her the right squeeze she wants when she is stressed during thunder storms.

great and small size fit Him perfectly.

she’s 43lbs of muscle and the L fits perfectly so the sizing is 100% correct.

MyPoor baby girl was never worried about any loud noises; until she was traumatized when she was outside in a thunderstorm & golf all sized hail started raining down

Only problem was the size

so maybe on the smaller size for a Shih Zsu, but measuring and following the chart is the best way to get the right size!)

We gave a 13 pound mix and the size was perfect again cut right into her throat and could not lay her head down

so sizing was very accurate.

The sizing isn’t good for racing dog bodies but more of a stocky bread

The Large size fits her perfect

I ended up using a child's size tshirt which worked better

A million thank you’s, Thundershirt!!!
